Title: Method and apparatus for stripping the components of a mixed sample from a trap
IPC: G01N1/34
Filed: 1970-09-10
Abstract: 1330149 Chromatography; laboratory ovens SHIMADZU SEISAKUSHO Ltd 10 Sept 1970 [30 May 1970] 43371/70 Heading B1X A method of collecting the components of a mixture separated by column chromatography comprises first fixing the components as concentrated bands in a stationary phase in a trap by the use of temperature gradients as described in Specifications 1204898 and 1204897, raising the temperature uniformly over the whole of the trap and effecting a pressure differential between the ends of the trap whereby the bands are stripped. The trap may be in the form of a chromatographic column attached to the outlet of the first mentioned column or may be the first column itself. The pressure differential may be set up by suction or by simple elution. As shown in Fig. 3 the trap 2 in which the bands are already fixed is housed in an electric oven 14. Stripping gas such as helium passes from source 10 via valve 20 once the desired temperature has been attained and the bands are then swept out to a detector before being analysed in a spectrometer, e.g. a mass spectrometer. The stationary phase(s) may be solid, e.g. alumina, charcoal or silica gel or liquid, e.g. silicone oil coated or impregnated into the supporting medium. The electric heater takes the form of a cylindrical aluminium block, Fig. 5 (not shown), embedded with cartridge heaters and having a radial groove which cooperates with a slot in an external thermal insulator. The whole is mounted on a support which can reciprocate to and from the column, Fig. 4 (not shown), such that the column may be located within the radial groove.

Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B17/00
Filed: 1962-11-16
Abstract: <PICT:1073603/C1/1> In a method of manufacturing flat glass in ribbon form by the float glass process the molten glass is caused to flow at a controlled rate from a channel in a free fall of 1 1/2 to 6 inches on to the surface of the molten metal bath. The channel may be a spout comprising a floor and side jambs.  The free fall of the molten glass from the lip of the spout to the bath ensures that the glass which has formed the upper surface of the glass on the spout continually flows forwardly into the upper surface of the layer on the bath, and the glass which has formed the undersurface of the glass in contact with the spout surface flows rearwardly under the spout thus forming a heel of glass and preventing the glass which was in contact with the spout surface from forming the bottom surface of the advancing glass layer so that bottom surface distortion, derived from physical contact of molten glass with the spout, is minimal. Molten glass 11 flows along a spout 3 which overhands the back wall 14 of a molten metal bath 15, and is allowed to fall on to the surface of the molten metal (e.g. tin or tin alloy). The overhang of the spout, permits the formation of a heel 36 of glass from the underlayer of molten glass in the spout.  The molten glass forms a ribbon 35 which is advanced along the bath and cooled by regulators 29 so that it can be removed without damage by rollers 27, 28 through an outlet 21 in the end wall 42.  A protective atmosphere is maintained over the molten metal.

Abstract: 969,007. Percussive tools. SKIL CORPORATION. Dec. 19, 1960 [March 30, 1960; April 4, 1960; May 18, 1960; May 31, 1960; June 1, 1960], No. 43550/60. Heading B4C. In a rotary and percussive hammer the drive for the tool includes a rotary cylinder and a striker reciprocating within the cylinder. The cylinder 26 (Fig. 1) is rotatable in a body 12 having a handle 15 and carrying an electric motor 70. The cylinder is driven from the motor by gearing 77, 78, 86, 87, 92, 24, the gear 77 carrying a pin 82 joined by a connecting rod 65 to a piston 64. A tool adapter 46, formed at 50 to carry the tool, has an octagonal shank cooperating with an octagonal bore 33 in a drive member 32 rotating with the cylinder, and extending into the cylinder to the zone of movement of a striker 58 which is reciprocated by movement of the piston 64. Leakage of air past the striker from the space between the piston and striker is compensated by air entering the space through a bore 100. Air is delivered to and exhausted from the space in front of the striker through ports 95, 98 and a duct 97. when the tool is not in contact with the work the adapter is held in extended position by the engagement of its shoulder 49 with an internal taper 55 in a nose 52 fixed to the body, and the striker moving beyond holes 124 is not reciprocated. The hammer may be adapted for percussive tool movement only by fitting an adapter with a circular shank. In the construction shown in Fig. 3 the hammer carries a chuck 120, which is rotated only, the chuck being screwed into the member 32 which is rotated by the cylinder, and its shank being too short to be struck by the striker. In a modification (Fig. 10, not shown) a spring is interposed between the piston and striker. The shanks of tools adapted for non-rotary operation may have squared portions or apertures so that the tools may be turned by a wrench or handle. Specifications 969,008, 969,009 and 969,010 are referred to.

Filed: 1960-12-20
Abstract: 969,895. Assembling force fits. R. HOE & CO. Inc. Dec. 20, 1960 [Feb. 3, 1960], No. 43711/60. Heading B3U. The mounting of bearing and torque transmitting elements on tapered shafts in which the bearing and element are hydraulically expanded and interference fitted on the shafts is characterized in that the shafts and elements e.g. a gear hub, are ground to accurate end dimensions with plus tolerance on the tapers, the gear hub being gauged to provide a predetermined axial sliding fit with the shaft so as to stop at a predetermined axial location, on the shaft when slid into position thereon, and then hydraulically expanded and forced into interference-fitting position whereby the desired interference fit is obtained regardless of which end of the hub engages first with the shaft in sliding fit position. In an embodiment the end d 1  of the shaft 1 and the internal bore D 1  of the hub 5 are ground to an accurately predetermined diameter within a tolerance of plus or minus 0.001 inch and both are ground to the standard taper of 1 in 12 within a plus tolerance of 0.0025 inch per inch of axial length. The hub is slid on to the tapered shaft to an accurately gauged position which is a predetermined distance L from a spacer ring 7 abutting a roller bearing housing already assembled on the shaft. The gear hub portions 5 on each side of the web 18 are then expanded by supplying fluid pressure to the bore 16 in the shaft and this enables the hub to be pressed further on to the shaft and into contact with the spacer 7 to effect the required force fit.

Title: Improvements in carbon products and in their production
IPC: B01J3/08
Filed: 1960-12-21
Abstract: Compacted graphite having a density of at least 1,9 g/cc. and a relative crystallite alignment not exceeding 70% is produced by initiating a <PICT:0918880/III/1> <PICT:0918880/III/2> detonating explosive round a mass of graphite.  In the Figures, 1 is a mass of graphite powder in a seamless steel tube 2 closed with stoppers 3, 4. 5 is a wrap of detonating explosive around tube 2, and 6 is a layer of detonating explosive around inert cone 7. 8 is an electric blasting cap.  In Fig. 2, explosive 5 surrounds a retainer element, e.g. cardboard tube 10, maintaining an annulus of water 11 between tube 2 and explosive 5.  One or more line wave generators 14 are attached to explosive 5 by taping around its periphery.  The whole assembly may be submerged in water as shown.  When blasting cap 8 is actuated, either explosive 6 or line wave generator 14 is initiated, which initiates explosive 5, the detonation then proceeding down the whole length of explosive 5.  This constricts tube 2 and compresses the graphite.  Explosives having detonation velocities of 4000 to 5000 metres per sec. are preferred, e.g. TNT, HMX, PETN, or nitroglycerine based explosives.  In place of the annulus of water (Fig. 2), cardboard or foamed polystyrene may be used.  To prevent the formation of cracks, the tube containing the compacted graphite may be heated to 400 DEG -500 DEG C. before removal.  Graphite may be produced in the form of rods, slabs, sheets, or tubes. The tubes are made round a steel mandrel which is removed by hand, or round a low melting alloy mandrel which is removed by melting. Specifications 863,194, 876,951 and 878,196 are referred to.ALSO:Graphite articles having a density of at least 1,9 g/c.c. and a relative crystallite alignment not exceeding 70% are produced by initiating explosion in a detonating explosive surrounding a mass of graphite powder.  The explosive surrounding the powder is preferably initiated at one end and substantially simultaneously at all points on the periphery of that end.  For uniform compression the graphite may be enclosed in a steel tube.  A liquid, e.g. water, may be interposed between the explosive and the tube containing the graphite, and the whole assembly may be submerged in water.  Graphite articles may be obtained in the form of rods, slabs, sheets or tubes.  The tubes are obtained by compressing the graphite round a steel mandrel which is removed by hand, or round a low melting alloy mandrel which is removed by melting.
